Nuhu Ribadu made a three-day working visit to the United States from May 4 to 6 to press for deeper security cooperation between Abuja and Washington, meeting senior U.S. officials and carrying a message of gratitude from President Tinubu to President Donald Trump.
During the trip Ribadu met U.S. Vice President J. D. Vance, the Acting National Security Advisor and Secretary of State, Marco Rubio, the Undersecretary for Political Affairs, Allison Hooker, and the Assistant Secretary of War, Daniel Zimmerim, according to the schedule of meetings released after the visit. The contacts were framed as part of a push to deepen Nigeria–U.S. relations on security matters and to sustain ongoing operational coordination.
The visit was explicitly described as a mission to deepen relations on security matters, and it included a personal delivery: Ribadu conveyed President Tinubu’s gratitude to President Donald Trump, according to statements about the meetings. The Nation Newspaper: "Nigeria has had mutual collaboration with the US in counterterrorism, defence cooperation, intelligence sharing, regional security, economic resilience, democratic governance and military training." The list of meeting partners and the subject matter of talks underline the political weight the trip carried in a short span.
That weight is measurable beyond protocol. A separate deployment of U.S. military representatives visited Maiduguri on May 20 — an AFRICOM delegation at Headquarters Joint Task Force North East, Operation Hadin Kai — to discuss intelligence sharing, intelligence surveillance and reconnaissance support, logistics interdiction and operational coordination in the Lake Chad Basin. And between May and July 2025 two of the deadliest terrorists in the country, Mahmud Muhammad Usman and Mahmud al-Nigeri, were arrested in an intelligence-led stealth operation coordinated among Nigeria security agencies. Both men, also known as Abu Bara’a and Mallam Mamuda, were leaders of the outlaw sect Ansaru.
Context matters: Nigeria is engaged in an asymmetrical war against insurgents and criminal networks, and the administration in Abuja has publicly argued that expanding cooperation with Washington is essential to make gains on the ground. The article says the collaboration between Nigeria and the US is gathering more momentum under the Tinubu administration — a claim that the meetings, the AFRICOM visit and the arrests together appear to illustrate.
The friction in this picture is the difference between diplomatic symbols and operational proof. Ribadu’s access to senior U.S. officials — including a meeting with the vice president — is a clear diplomatic result. But the public record does not map each operational success to those meetings. The arrests of the Ansaru leaders occurred between May and July 2025; officials say the arrests were carried out by Nigerian security agencies in an intelligence-led operation. Whether Ribadu’s trip directly produced specific operational outcomes is not detailed in the available accounts.
What follows is concrete: Nigeria’s security and diplomatic teams now have a freshly signalled pathway to Washington’s senior civilian and military interlocutors, and U.S. engagement in the region continued immediately afterward with the AFRICOM delegation’s May 20 visit to Maiduguri. That sequence — high-level meetings, an AFRICOM delegation on the ground, and the arrests of two Ansaru leaders — suggests a tightening of political and operational coordination that Abuja says it will pursue.
Ribadu returns to Nigeria carrying a clear message and new access. He left with a public tally of meetings at the very top of the U.S. government and with the task of translating those contacts into sustained operational cooperation. For a country fighting asymmetric threats, the practical measure of success will be whether the momentum the Tinubu administration says exists turns into fewer attacks and more dismantled networks; for now, the trip added diplomatic muscle to a security agenda already producing arrests and coordination on the ground.
